Mapping multi-repo architecture without losing the big picture
Multi-repo systems become hard to reason about when architecture lives across disconnected READMEs and handoffs. A graph view keeps the relationships visible.
Multi-repo systems create a documentation problem as much as a code problem. Each repo can look healthy on its own while the platform-level picture stays fuzzy.
That makes onboarding slower, architecture reviews noisier, and AI tooling more brittle because the relevant context is split across repositories.
Why READMEs alone are not enough
READMEs are still useful, but they rarely show how repositories relate to one another. Teams end up reconstructing the same architecture mentally every time a cross-cutting task appears.
A better default
The practical fix is to treat the repos and their documentation as one system-level graph. That way engineers and agents can move from a question to the right repo path faster.
